Joint Theoretical and Experimental Electron Momentum Spectroscopic Studies for DNA Bases. The study of DNA structure is an area of intense research activity and continues to reveal new levels of complexity and diversity. Recent experiments (Science, 2002) provided direct evidences of the adenine non-planarity, indicating non-rigidity of DNA bases.

The study of DNA structure is an area of intense research activity and continues to reveal new levels of complexity and diversity. Recent experiments (Science, 2002) provided direct evidences of the adenine non-planarity, indicating non-rigidity of DNA bases. Electron momentum spectroscopy (EMS) has been identified to be an appropriate technique in the study of chemical binding mechanism and orbitals at molecular level. The aims of the project is to study orbitals and interactions of DNA and RNA bases such as adenine, thymine (uracil), guanine and cytosine using momentum space quantum mechanics and EMS experimental techniques. The outcome of the project will improve our understanding of the DNA double helical strand structure.Read moreRead less

Synchrotron science is a priority area for Australia, the USA, and most first world countries. Development of new ideas and tools for X-ray investigations is the key to future opportunities and is the subject of this proposal. We will develop new techniques for crystallographic electron-density studies, X-ray Anomalous Fine Structure (XAFS) and Multiple-wavelength Anomalous Dispersion (MAD), and provide useful advances for X-ray lithography and radiography. Simultaneous investigation of form factors, absorption coefficients, anomalous dispersion and X-ray scattering will provide new experimental tests of relativistic atomic wavefunction calculations, molecular bonding and solid state coupled cluster theory. Major discrepancies will be resolved.Read moreRead less

Shape-Shifting Molecules: Photoisomerization Action Spectroscopy. This project aims to examine molecules that change shape in response to light in order to gain insight into the biological processes they control. Many biological systems, including the human visual apparatus and bacterial photosynthesis, depend on molecules that change shape in response to light. The project plans to probe shape-shifting molecules with laser light while they are propelled through gas by an electric field.

This project aims to examine molecules that change shape in response to light in order to gain insight into the biological processes they control. Many biological systems, including the human visual apparatus and bacterial photosynthesis, depend on molecules that change shape in response to light. The project plans to probe shape-shifting molecules with laser light while they are propelled through gas by an electric field. Light-induced changes in molecular shape produce detectable variations in drift speed. The ensuing knowledge would help calibrate computational approaches for predicting molecular function. It would also establish foundations for understanding essential biological molecules, including retinals, carotenes and peptides, and for developing new light-activated molecular motors and switches.Read moreRead less

Spin detection and control in molecular nanomagnets at surfaces. One fact of computing life is that there's never enough storage. Storing information on single molecules would improve storage density by a factor of 10,000. A promising strategy is to arrange magnetic molecules on a surface, so that their spin can be accessed from one side in read/write operations. While much is known of magnetic molecules in crystals, their behaviour on a surface is still a puzzle.

A promising strategy is to arrange magnetic molecules on a surface, so that their spin can be accessed from one side in read/write operations. While much is known of magnetic molecules in crystals, their behaviour on a surface is still a puzzle. Using mathematical models and synchrotron experiments, the project will explore which combinations of molecules and surfaces exhibit the best magnetic behaviour. The expected results will be crucial for the development of a new generation of high-capacity and high-performing computers.Read moreRead less
